摘　　要：通过田间试验研究了氮、磷、钾配施对贵草1号多花黑麦草产量、品质的影响。结果表明:氮、磷、钾肥的合理施用能显著提高贵草1号多花黑麦草的鲜草产量,施肥的增产效果依次为施氮>施钾>施磷。氮、钾肥的施用对贵草1号多花黑麦草品质的影响明显。综合各处理的产量、质量以及经济效益,贵草1号多花黑麦草最佳施肥方案为N8kg/667m2,P2O54kg/667m2,K2O3kg/667m2。Guicao 1 was tested under different combination of N, P and K amount to study the effect on its fresh grass yield and quality. The results showed that the rational combination of N, P and K amount can significantly increase its fresh grass yield and the increasing yield effect of N, P and K fertilizer is N〉P〉K, and N and K fertilizer has the significant effect on its quality. The optimum balanced application design is 8 kg/667m2 N, 4 kg/667m2 P2O5 and 3 kg/667m2 K2O.
